Answer:
Ectotherms have the highest mass and the Endotherms have the lowest
Many species are similar, if common names are used people will get confused
Answer: 5.138 × 106
Explanation:
1.Move the decimal place to the left to create a new number from 1 up to 10.
2. Determine the exponent, which is the number of times you moved the decimal.
3. Put the number in the correct form for scientific notation (N*10^a)
Where N equals between 1 and 10, but not 10 itself, and a is an integer (positive or negative number).
Natural selection is the process by which species adapt to their environment. Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring. Simply put, natural selection is a consistent difference in survival and reproduction between different genotypes, or even different genes, in what we could call reproductive success. [A genotype is a group of organisms sharing a specific genetic makeup.]
Most probably these scientists will do more studies and experiments in order to learn more about the subject. For example, if they compare plastic grocery bag with paper grocery bag it is important to investigate which one is a better resource use in the life cycles, which one is better for manufacturing or whether one of them can be reused. There are many questions about this issue.
